Crayon Carvings

I found some old crayons in my old art supply box, so gave it a try on carving on it with dual tone colors

1.Old crayons

2.Shredder

2.Detail Pen

Now you can carve anything that your mind tells you, I've attached this pic only for an example

Shred various crayons for better visuals

Now fill the carved ares with the shredded crayons, remember to use the opposite color of the base crayon

Now, clean away the extras to make it look good
